One thing that everyone seems to be missing is that the M and the A lenses may provide different results wrt color. That may be an issue for some people under some circumstances, such as photographing the same subject using the different lenses. IOW, the benefit of using one series or another may outweigh whatever benefit there is to using both. Personally, I like the idea of all my lenses, at least for a particular photo session, to behave similarly.

I've compared M & A before and personally find the difference is meaningful. YMMV.
